2024年10月15日 · BSSS are among the most common benign EEG variants, appearing in 1.85% to 24% of scalp EEG recordings. BSSS are usually observed in adults and seldom in children. Until the early 1990s, BSSS were considered epileptogenic. However, a 1991 study by Molaie et al concluded that BSSS are likely benign variants. A more recent study by Issa et al ...

Benign epileptiform transients of sleep (BETS) are also called small sharp spikes (SSS). While BETS have a slightly oxymoronic name, they are in fact a normal, benign finding that you can see in the drowsy and asleep states.

appearance. occur in stage 1 or 2 NREM sleep. usually monophasic, occasionally diphasic. temporal with broad field of distribution There is typically no disturbance of the background, although there is sometimes a single aftergoing slow wave.

Figure 1. BSSS (aka BETS) on ipsilateral ear reference (left) and longitudinal bipolar montage (right). Note steep descending slope of low-amplitude spike and small after-coming slow wave, particularly at T7 to TP11. BSSS are a common feature …

2013年9月5日 · There are many variants on EEG that are considered normal and yet might be confused with epileptiform activity. These benign EEG variants are often found in only certain subpopulations: either young or old patients or patients with …

2019年3月2日 · Benign (normal) EEG variants are spiky or rhythmic activity in EEG that do not have clinical significance. Benign variants mostly occur during drowsy and light-sleep stage. Spiky benign variants are: 14 and 6 positive spikes, generalized max posterior temporal, 12–20 years of age, drowsy state

Benign sporadic sleep spikes (BSSS), also referred to as small sharp spikes or benign epileptiform transient of sleep (BETS), are low amplitude (<50 mV), brief (<50 ms), sharply contoured monophasic or biphasic electronegative spikes …

2021年6月1日 · Firstly, the detection of BEVs depends on the type of EEG recording (standard versus prolonged EEG) and the sleep duration. Fourteen- and 6-Hz positive bursts, BSSS, and POSTs are exclusively seen during sleep.
